CLEANER FEEDER FOP GOTEUN GINS.

Application filed april a5, ieee.

To all whom t may concern.'

Be it lrnown that I, JOHN A. STREUN, a citizen of the United States, residing at Sherman, Texas, have invented a certain new and useful Improvement in Cleaner Feeders for Cotton Gins, of which the following is a specification.

My invention relates to an improvement in cleaner feeders for preparing the cotton for ginning. Tt is applicable to gins of the ordinary construction and is intended to break up and `cleanthe cotton, and so distribute it that it will be fed evenly to the gin in a clean condition.

u It is an object of the invention to provide an apparatus for agitating and breaking up the cotton and acting upon the cotton by a draft of air so as to remove the particles of dust and chaff more fully from the cotton before it is fed to thegin. Y

Another object is to distribute the cotton in `an even and uniform flow to the gin. The device shown in the 4drawing is an improvement upon my priorPatent No. 1,473,- 0594 granted November G, 1923.

Referring to the drawing herewith Fig. 1 illustrates a vertical section through a cleaner feeder embodying my invention. Fig, 2 is a broken detail illustrating the `1:50 arrangement ofy the picket teeth upon the blades of the cylinders. Lilie numerals of reference refer to lilre parts in both views. In feeding` cotton to the ordinary gin it is desirable that the ordinary `dirt and trash be removed from the cotton and the lumps and balls of seed cotton be broken up and distributed before being passed to the saws of the gin. This resultsnot only in a better `ginning of the cotton, but in the production of a cleaner and more valuable staple. The purpose ofthe present device is to break up and agitate the cotton before it is `fed to the. gin, and to thoroughly clean the cotton of the particles of dust, sand and trash therein. In carrying out this purpose, the cotton is discharged to the cleaner by means of a hopper 1 onl the uppei` end of a casing 2. The casing is supported by brackets 3 and 4 upon the upper side of a gin 5. j

The cotton entering the hopper lfalls upon two feeding rollers 6 which are mounted upon shafts 7, 7 supported in the sides of the casing 2. These rollers have radial blades 8 and are adapted to. rotate in opposite directions as shown in the arrow Serial No. 708,961.

in the drawing so as to feed the cotton down between the rollers in a compact bat. These rollers are adjusted to operate at a slow rate of speed so as to allow the agitating members to thoroughly clean the cotton thus fed to them before the cotton goes to the O`in. g

Below the feed rollers 6 is a cylinder 9 mounted upon a shaft 10 for rotation. This cylinder is constructed of baffles or blades 11 mounted approximately tangential to the shaft 1() as shown in the drawing, and have spacing and reinforcing plates 12 arranged longitudinally of the adjacent blades 11 so as to provide, in effect, a polygonal cylinder with short blades 11 projecting from the angles thereof in the manner shown.

ends of the blades 11 have of spaced pins or pickers 13 rotates in the direction of the arrow to carry The thereon a series Said cylinder the cotton removed from the lower end of the bat 1n a direction toward a cleaner casing to the rearthereof.`

Secured upon the rear of a cleaner casing 20.

Mounted rotatably the casing 2 is It is constructed in the same manner as is the cylinder 9, and is adap the saine direction.

S5 ted to rotate in The shafts 10 and 16 are so spaced as to have the teeth 13 upon the blades of the two cylinders interfit as shown in Fig. said teeth being staggered relative to each other so as to allow them to interfit as shown in the drawing.

The cylinder 15 is above and to the rear of the cylinder 14. It is mounted on shaft 17 for rotation in the same two previously mentioned,

direction as the cylinders. The

teeth 13 on the blades interfit with those of the cylinder 1,4 in the same manner as do those of the cylinders 9 and 14 previously described.

Above the cylinder la is an agitating rollr er 18 mounted for rotation with shaft 19 in a direction opposite to that of the other cylinders.

It is constructed as are the cylinders 9, 14C and 15, but is inateriallysmaller and is spaced from the two cylinders 14 and 15 to allow the passage of cotton between said roller and the adjacent cylinders without materially damaging the cotton.

The casing 20 in which t he cleaning cyl `110 v indersand the agitating roller are mounted, is shaped toy house the cylinders lll and l5 and the roller 19 fairly closely. The upper portionof the casing. is formed into a door 21 hinged at 22 so that it may be lifted to expose the cylinders for cleaning or repair, the door extending` to the rear and terminating at 23.

Beyond the door and lower end of the casing is the sheet iron plate 2aconnected to the upper end of the trough 25 in which operates a screw conveyor 2G. The said conveyor acts to dis charge chail and dirt through an opening on the side of the casing.

Vithin the casing `is a screen connected with the cross member 2S adjacent the door and spaced uniformly from the outer peripherics of the cylinders so as to surround the threey cylinders 9, lf-land 15 on the underside thereof, said screen being attached at its torn-"ard end to the supporting .member 29 at the mouth of the opening 530 to the chute ,31. Between its ends the screen is secured for support to cross bars 32 and 33. `Belowthe screen 27 in the casing 2 is a second screw conveyer 34 acting to discharge' the chaff and dirt at the side of the machine.

In the operation ofthe device, cotton will be fed downwardly between the rollers (i in a uniform compresse-d batagainst which the teeth 13 on the blades 1l of the cylinder 9 will contactand tear olf therefrom small lun'ipsor wads of cotton, throwing` it rean wardly upon the cylinder 14. The teeth i3 upon the 'two lcylinders will intermesh in suoli a manner as lto prevent-the cotton. from beingfcarried around the-cylinder 9 and discharged to the gin before it is yproperly cleaned. The .cylinder lll will engage the cotton carryingitto the rear upon cylinder 15 rEhe blades ofgthc cylinders will act fans and the c ylinderswillbe rotated at such speed as to cause a material draft of air, tending'to throwthe cotton outwardly from the cylinders soas to break it'up and loosen it so that the dirt may :be shalen out of the cotton. The agitator roller 19 will obstruct the free passage of the cotton thrown from the cylinder lll and will tend to break up the 4wads or bolls of cotton and distribute it more evenly through the length of the roller. The peripheral speed of the roller 18 will be' slightly less than that ot' the cylinders 14 and 15, and will tend to Vfeed the cotton toward the cylinder 15 in an even J(low. The cotton. will be carried from the agitating roller 1S over the cylinder 15 against the `screen 27 and will thus be carried back against the cylinder 14, and as it lpasses over the ridge or hump in the screen above the cross piece 3Q, will be turned over and as it is engaged by the extending to the -lolades kof the `cylinder 14, will be again thrown outwardly and the chaff and dirt therein will be blown .througl'i the screen toward the lower part of the casing. The casing is open at the sides thereof adjacent the screw conveyor 26 and the chaff and dirt will be scraped and blown from the casing in an obvious manner.

As the cotton passes from the cylinder ift, it will be again turned over and engaged by the blades of the cylinder 9 and thrown to chute 31 to be delivered therefrom to the gin. Dirt and chaff blown .through the screen below the cylinder 9 will be carried away through the screw conveyor 531i and the strong craft caused by the rotation of the cylinder will assist in the eliniination of the impu *ities of the cotton.

The forming of the cleaning cylinders in this device in the manner described, results in a more thorough agitation and cleaning 1,1

of the cotton without material damage to the libre. The blades of the cylinders act as fans to agitate and break up the cotton and to blow the dirt andchaif from the cotton staple. lt has therefore a larger cleaning capacity for ,the cotton because of the draft of air caused by the rapid rotation of the cylinders, and vfurther through the fact that thc cotton being engaged by the blades of the cylinders instead of by spikes such as are employed on ordinary cleaning devices, will not` damage the cotton. The action of the agitating roller 18 in combination with the cleaning cylinders in the manner described, results in a cleaner cotton more evenly and smoothly distributed than is customary in the ordinary type of cleaner feeder.

Further objects and Aadvantages will be apparent to one skilled in the art without further description.
